After many years reading this forum I have now registered just to answer this debate. I've read quite a few posts that start "I'm not an engineer
but my dad blah blah blah" . Well when not messing around with my own boats I work as a super yacht engineer
(AMSA and MCA) and this hoax has been going around the automotive and marine
industries for 40 plus years. And before anyone says do the maths, I did, as a second year electrical
apprentice. Now Im just waiting for some to claim they have built a perpetual motion machine! Physics cant be cheated.
